HANGER FOR SAW-FRAIVIES.

SPECIFICATION forming part of Letters Patent No. 389,470, datedSeptember 11, 1888.

Application filed March 6, 1888. Serial No. 266,314. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. HEwE'r'r,

of Brandon, in the county of Rutland and State of Vermont, have inventeda new and useful Improvement in Hangers for Saw- Frames; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

In the sawing of marble or other kinds of stone into slabs a gang ofsaws held in a suitable frame is used to accomplish the purpose, andthis frame carrying the saws must be supported so as to havereciprocating movement in relation to the material to be sawed, and inorder to do this the frame has to be pivoted so as to swing back andforth, and thuscause the saws to out into the material at eachreciprocation. Heretofore it has been customary to support the saw-framein numerous ways, the best known of which is to have arms pivotallyattached to the sides of the frame and pivoted at their other ends tosuitable supporting-posts.

The present invention relates to an improved hanger or support for theframe carrying the gang of saws, and my object is to provide a simpledevice which shall support the frame so that it can have the desiredreciprocating movement with a minimum amount of friction.

The invention therefore consists of various details of construction andin the arrangement of parts, all hereinafter fully described andparticularly claimed.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of my improved hanger-box, and Fig. 2 isacentral vertical section of the same. Fig. 3 is a section on line 00:10, Fig. 2.

In the drawings, Ais the hanger-arm,suitably attached at its upper endto a supportingbeam. The lower end of this arm is screwthreaded and isadapted to be screwed into cap B, which it supports. A jam-nut, a, isprovided near the end of the hangerarm, and acts to prevent the arm Afrom working out of place. The cap B is made narrow at the top, where itis attached to the hangerarm, and wider at its lower part, adapted toreceive the head of the base-pieceO, which is attached directlyto theframe supporting the gang of saws. The base-piece '0. hasdownwardly-extending arms, the lower ends of these arms being bolted orotherwise secured to the sash of the gang of saws. (Not shown.) The headof the base-piece is rounded, so as to fit within the socket in the capB, and this head 0 has secured in its sides steel pivot-cups b 1),adapted to form bearings for shafts d d, which pass through the sides ofthe cap B, thus supporting the base-piece, and through it the saws, butallowing it pivotal movement, thus giving to the gang of saws thedesired reciprocating movement. I make the head 0 of the base-piecehollow and provide an opening in the top adapted to register with anopening, 6, fitted with a suitable plug near the top of the cap B, andthis head a, I fill with cotton waste, and by pouring in oil through theopening 0 the filling will be saturated, and thus the bearings of theshafts d d in the steel cups will be kept lubricated.

It will thus be seen that by my construction the sand and water which isfed from above to the saws cannot get into the bearings upon which thesaw-frame moves, since the cap B, which supports the frame, acts as ashield for the bearings.

I claim as my invention- 1. A hanger for saw-frames, consisting of acap, B, suspended from a suitable support, and a base-piece secured atits lower end to the saw-frame and pivoted at its upper end within thecap B, substantially as described.

2. A hanger for saw-frames, consisting of a cap, B, suspended from asuitable support, having a socket in its lower end, the basepiece 0,having a rounded head adapted to fit within the socket of the cap B,said head having steel pivot-cups secured in its sides, and pivots d 01,extending through the sides of said cap, their inner ends bearing insaid pivotcups, substantially as described.

3. A hanger for saw-frames, consisting of a cap, B, suspended from asuitable support, having an opening near its upper end and a socket inits lower end, the base-piece C, having arounded head pivoted withinsaid socket, In testimony whereof I have signed my name as described,said rounded head being formed to this specification in the presenceoftwosubhollow for the reception of cotton waste or i scribing witnesses.

other like material and having an opening at l CHARLES E. HEWETT.

all substantially as and for the purpose del .CHARLES H. JOYCE,
